Digitac PSU/Controller MP1

The Digitac access psu/controller contains the power supply and electronic circuitry for an access control system which is operated from a ten digit entry keypad mounted outside the protected area. The control unit is mounted in a secure area. The ten codes held in the memory of the system have different first digits to denote the different levels of security and can be changed easily and as often as required by authorised personnel. Each code can have from four to seven digits. This plus the fact that the code is neither accessible nor visible provides a relatively high level of security on a simple system. The memory is protected by a key operated switch on the main control unit. The code can be changed by inserting the key and turning it to the programming position. Any or all of the existing ten codes can be changed by following the procedure in the instruction manual. The new codes are confirmed in the system simply by returning the key to the 'ON' position and removing the key.
